Shared Folders in Server now require password?

Situation
1 An Active Directory (AD) have numerous Registered Users (RU) to the Domain (DM) using Server 03 SP2.
2 Numerous PC running XPWin SP2 had joined the Domain and appears as PCs in the AD User / Computer dialog at the Server.
3 Numerous Shared Folders (SFd) in the Server are being shared allowing RU to access.
4 When a RU logon to the DM from one the the PC, after entering the his password, RU can access all the
SFd without further request from password; this is normal.


Issue
1 After a power failure, RU can still logon to the DM BUT...
2 To access the SFd, User password (PWd) will be asked.
3 After a number of tries of knocking with the PWd, RU can then access the SFd.
4 But on restarting the Server and the running PCs, the problem of of PWd reappear.

Note
1 Pinging with the TCP/IP address among all the PCs and server in both in/out has no problem at all.
2 One of the PC attached to another Switch don't seem to have this problem.


Question
1 How to check what's happening?
2 How to solve this?
Thanks in Advance.

 

And this power failure was on what? The workstation? Hopefully not the Server!

On the work station.
1. Remove share
2. reboot
3. confirm share is gone
4. reshare

Thanks Mike, good to see u again

It is actually a lightning strike with power off thus all pcs shutdown except the server which has backup power remains running. However i am not sure if there is any power surge on the server that may have corrupted the files.

Meanwhile I have the following important finding :
When a RegUser tried to access a shared folder in the server, when password is required & if i use the existing RU name, sys responses that the current RU has already login, thus another User name must be used before the Shared folder can be accessed.

Re Yr suggestion, don't understand how to remove share (shared folder in the server) from the workstation?
